FEEDING ATTACHMENT FOR SLUG OR TYPE CASTING MACHINES.

Specification of Letters Patent.

Patented Mar. 21, 1911.

Application filed January 20, 1910. Serial No. 539,035.

To all whom it may concern:

Be it known that I, JAMES G. RAUoH, a citizen of the United States, anda resident of Slatington, in the county of Lehigh and State ofPennsylvania, have invented a new and Improved Feeding Attachment forSlug or Type Casting Machines, of which the following is a full, clear,and exact description.

Among the principal objects which the present invention has in view are:to provide means for delivering pigs of type metal to the melting pot atintervals coincident with the withdrawal therefrom of quantities ofmelted metal equaling in weight the said pigs; to provide means wherebythe rate of adjustment may be varied to suit the action of the castingmachine; to provide a construction whereby the feeding mechanism may beremoved from over the melting pot; to provide means whereby the metalmay be delivered into the melting pot without splash of the molten metaltherein contained; and to provide a mechanism of the character specifiedwhich is simple, efficient and durable.

One embodiment of the present invention is disclosed in the structureillustrated in the accompanying drawings, in which like characters ofreference denote corresponding parts in all the views, and in whichFigure 1 is a side elevation of the feeding mechanism constructed andarranged in accordance with the present invention, and showing infragmentary form parts of the type or slug casting machine to which thesaid feeding mechanism is connected; Fig. 2 is a vertical section of theupper and hinged end of the feed table taken on the line 22 in Fig. 3;and Fig. 3 is a plan view of the invention on an enlarged scale andillustrated as broken and contracted near the median line.

In Fig. 1 of the drawings the side bar A and the lever end B are partsof the ordinary linotype machine. The present feed ing mechanism ismounted upon the side bar A by means of a standard 4, the lower end ofwhich is bent to form a foot 5, suitably perforated to pass a bolt 6,which is extended through an ear 7 formed on the side bar A of thelinotype machine. Extended laterally from the standard 4, and at theupper end thereof, is a hub 8, perforated to receive a pivot shaft 9,which is also extended through brackets 10, 10. The brackets 10, 10 aresuitably mounted upon the sides of a platform 11. It is upon theplatform 11 that the feeding chains and guide pulleys therefor aremounted. By means of this construction the platform and parts carriedthereby may be lifted and swung on the pivot 9 to raise the extended endof the platform 11 from over the melting pot C, in which position it isplaced when in operation, as shown in Fig. 3 of the drawings.

The platform 11 is provided with a drum 12 at the forward end thereof,and upon the upper surface with a sliding plate or shoe 13. The plate 13is disposed on the platform 11 to aline with the upper surface of thedrum 12. The drum 12 is mounted upon a shaft 1 1, at the ends whereofare fixedly attached sprocket wheels 15, 15 to be engaged by sprocketchains 16, 16. The chains 16, 16 are suitably connected by cross bars17, 17, the bars being spaced each from the other the distance requiredto receive the under side of the pigs D, D which, in the operation ifthe machine, are placed between the said ars.

The two sprocket chains 16 and the cross bars 17 constitute the conveyerwhereby the pigs D, D are forced gradually forward over the platform andplate 13 mounted thereon, to be finally delivered over the drum 12 to aninclined chute extended into the melting pot C. The sprocket chains 16,16 are reeved over sprocket wheels 18, 18, which are fixedly mountedupon a shaft 19, mounted 011 the upper end of the platform 11. The shaft19 is the power shaft of the present mechanism, and is driven by aratchet wheel 20, which is fixedly secured to the said shaft 19. Theteeth formed on the wheel 20 are suitably fined to permit a large scopeof adjustment of the feed for the conveyer formed by the chains 16, 16.The wheel 20 is rotated by a lever 21, which is pivotally mounted uponthe shaft 19, as shown in Fig. 1 of the drawings, and has mountedthereon a pawl 22 adapted to over-ride the teeth formed in the wheel 20.The pawl 22 is seated on the periphery of the wheel 20 by a spiralspring 23, anchored to both the said lever 21 and the pawl 22, in themanner shown in Fig. 1 of the drawings. The lever 21, in rotating thewheel 20, is oscillated about the shaft 19 in a larger or smaller are,as the case may be.

The oscillation of the lever 21 is produced bythe lever B, or othersuitable reciprocating or rocking member of the linotype or type castingmachine to which this invention is applied. The operative connectionbetween the lever B and the lever 21 is a connecting rod 24. The rod 24is connected to the lever 21 by a pin 25 set out from the side of thesaid lever 21, and to the lever B by a perforated eye-bolt 26 adapted tofreely pass the rod 24. At the under side of the eye-bolt 26 is disposeda movable collar 27. The collar 27 is fixed in adjusted position uponthe rod 24 by a set screw 28. The reason for the connection by means ofthe eye-bolt 26 and the collar 27 shown and described, is to permit anyadjustment whereby the lever B is allowed to move to an extreme forwardposition without lifting the rod 24, and to govern the extent of themovement of the rod 24 by the lever B at the opposite end of the strokeof the said lever, as shown in dotted lines in Fig. 1 of the drawings.

The forward stroke of the lever 21 is governed by a set screw 29. Thescrew 29 is suitably mounted in an extension 30 of a bracket 31. It isobvious that by the extension or withdrawal of the screw 29 through thethreaded extension 30, the upward lift of the lever 21 is limited andcontrolled. The lever 21 is lifted against the end of the screw 29 by aspiral spring 32, one end of which is threaded through perforations 33in the end of the lever 21, and the other end of which is engaged with apin 34 set out from the side of the platform 11.

The platform 11 is constructed of suitable and desired length. Betweenthe bars 17, 17 are placed the metal pigs D, D. In its lowered conditiona support for the forward end is required. This I prefer to provide inthe form of a bracket rest.

With a mechanism constructed and arranged as above described, and asshown in the accompanying drawings, loaded with the metal pigs D, D, inthe manner stated and shown, the operation is as follows: lVith eachoscillation of the lever B, which in the present instance is connectedwith the line casting mechanism, the rod 24 is depressed at the free endthereof a distance regulated by the position in which the collar 27 isplaced on the rod 24. When the lever 21 descends, the wheel 20 isrotated by the pawl 22, which is in engagement with the teeth of thesaid wheel. The rotation of. the wh eel 20 advances the chains 16, 16and bars 17, 17, and the pigs D, D, held therebetween, carrying the pigsgradually to the end of the platform 11 and drum 12 thereon mounted.When in the operation of the type casting machine of which the lever Bis a member, an amount of type metal has been removed from the meltingpot C equal in weight to the pigs D, D, the conveyer and wheel 20operating the same are arranged to deliver to the said pot C one of thepigs mounted thereon. In this manner the melting pot of the machine isautomatically and constantly replenished, removing the difficultiesattendant upon the exhaustion of the melting pot through inattention onthe part of the operator and the failure to cast the lines set up orforms provided for casting lines of type. It will be understood that themovement of the rod 24 is controlled so that the chains 16, 16 will'bemoved the distance required to deliver the successive pigs as and whenthe needed number of lines of type or slugs have been cast from themolten metal withdrawn from the pot C. It will also be understood thatthe adjustment of the rod 24 necessary to accomplish this is by settingthe collar 27 and manipulating the screw 29, the one regulating theextent of the downward movement and the other limiting the extent of theupward movement of the lever 21.

It will be understood that the conveyer and platform 11 may be placedupon the machine at any suitable and convenient position. Thatillustrated in Fig. 3 of the drawings is considered by me the mostadvantageous. The delivery end of the conveyer is advanced over the topof the pot C and at one side of the center thereof to avoid the plungerrod with which the melting pots of linotype and other type castingmachines are provided. It is to prevent the splash of the molten metalwhen the pigs are dropped therein that I have provided an inclined chute37. The chute 37 is illustrated by me in Figs. 1 and 3 of the draw- 1ings as independently mounted on the bar A. I prefer such an adjustment,although it will be understood that the standard 38, supporting theinner end of thechute 37, may be extended from the side rails of theplatform 11. The standard 38 is provided with a series of perforations39. The perforations 39 are adaptedto pass the shank of a bolt 40,whereby the said standard is secured to the side bar A. The series ofperforations 39 are provided to permit the adjustment of the chute 37 tochange the angle of travel thereon of the pigs, thereby reducing thespeed at which the said pigs are delivered to the pot G. This controlsthe delivery of the pigs to the pot C and completely avoids thesplashing of the hot metal by theintroduetion of the said successivepigs. The chute 37 is hingedly mounted on a pivot pin 41, whereby thechute may be lifted back from over the pot C to permit any necessarymanipulation or repair thereof.

The operation of the invention is obvious. After the rod 24 has beenproperly adjusted to give the proper rate of travel to the chains 16,16, all that remains for the operator to dois to see that the pigs D, Ddo not become exhausted in'the conveyer. This does not require-theconstant or alert action demanded by the present system. The pigs may besupplied on the conveyer in many or few numbers. Further, if bycarelessness or inadvertence the conveyer should become exhausted, thiscould be replenished before the melted metal would be exhausted in thepot C, for the reason that the maximum supply of the metal in the pot Cis maintained constant by the feeding attachment for type castingmachines herein described.

Having thus described my invention, what I claim 13S new and desire tosecure by Letters Patent is 1. A feeding attachment for type and slugcasting machines, comprising a receiving platform; a plurality ofsprocket chains disposed adjacent to said platform; a plurality ofsprocket wheels mounted on said platform to receive said chains; aplurality of cross bars extended between said chains and adapted to passover said platforms, said bars being separated to form pockets for leadingots; a driving mechanism for said sprocket wheels and chains; and atransmission mechanism connecting said driving mechanism and the drivingmechanism of the casting machine upon which said casting is mounted foroperating the driving mecha nism and chains connected therewith inunison with the operation of the casting machine.
